OK, so the chiller worked fine, but, my plastic siphoning device melted in the recently boiling wort. It was one of those auto siphon pumpy thingys (about $15) and I really liked it. I had to break it in half multiple times to keep drawing off the bottom of the kettle and restart the siphoning manually (orally?) multiple times as well. Nice cold wort on the other end but a major hassle of a process. Any advice or equipment to do this better next time? What do you have dipping into your hot wort that doesn't melt? Also, the hot side tubing is pretty discolored now.

Oh, to clarify, I purchased a counterflow "plate" chiller similar to this one:
